Telltale Signs of Dirty Air Ducts

April 16th, 2017

As your go-to experts in air conditioner repair among our 24-hour plumbing services, we at Expert Services- Plumbing, Heating, Air & Electrical have seen every possible air-related issue. One of the most common and important: Dirty or contaminated air ducts.

The idea of air conditioning and air ducts in the home or business is to provide clean and filtered air, but contaminated ducts can actually make indoor air quality worse than outdoor air. Here are some common signs that you might need to call our experts to examine or clean your air conditioning ducts.


If there’s visible mold present anywhere near your air vents, there’s a very high chance that it’s present in much larger quantities within the ducts themselves. Mold flourishes when cool moisture is present, and it can lead to a number of very serious health complications, including severe asthma and allergic reactions. It’s commonly caused by air ducts that are leaky or poorly insulated, or faulty condensation pans.


When you turn your air conditioner unit on, do you often notice small clouds of dust popping out of the vents as it starts up? This can mean your ducts are full of debris and dirt that’s built up over time, and this dirt becomes part of your air when it’s spread around.

This can lead to aggravated allergy or asthma symptoms, and in a non-health area, it can also lead to heavily increased energy bills due to lost air. There are times where this will just be caused by a dirty filter that needs a simple and inexpensive replacement, but in other cases, it can signal leaks or clogs in the ducts that will require our professional repair services.


Whether it’s insects or rodents, a pest infestation can be another major cause of duct issues. They’re often the root cause of dirt in the ducts, and the feces left by various pests can lead to health issues. You’ll typically be alerted to pests when you see their droppings – or in the case of rodents, you may hear them in the ducts. Any infestation requires immediate exterminator services first, and then our professional cleaners can come in and make sure your ducts are safe to resume air service.
